Researchers find a viral symbiont of a protozoan parasite increases virulence to the human host.
When humans have parasites, the organisms live in our bodies, co-opt our resources, and cause disease. However, it turns out that parasites themselves can have their own co-habitants.

Researchers have developed a bacteria strain that is uniquely effective at degrading the toxic industrial chemicals known as PCBs, or polychlorinated biphenyls.
PCBs are toxic man-made organic chemicals that pose a threat to human health and to the environment.

Lasers are the new DNA. It is called matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) and it uses mass spectrometry to quickly test for hundreds of different pathogens in a small sample using a single automated device. MALDI-TOF is increasingly being used in clinical micr... Read More
A sample of raw pork products from supermarkets around the United States found that yersinia enterocolitica, a lesser-known food-borne pathogen, was present in 69 percent of the products tested, according to a study released today by Consumer Reports.
The bacteria infects more than 100,000 ... Read More
Researchers at the University of Liverpool's Institute of Infection and Global Health (IGH) have discovered a common cause of heart damage in patients with sepsis.

Little attention has been paid to the use of antibiotics in the aquaculture industry as one reason for the increase in bacteria resistant to antibiotics and the spread of such resistance to other bacteria.
Since the antibiotics that are used in veterinary medicine and aquaculture belong to t... Read More
Acid-loving bacteria thrive in sour, acidic places and can help to dissolve metal. Therefore they are often used for industrial metal extraction. In her doctoral thesis "Growth and Survival of Acidithiobacilli in Acidic, Metal Rich Environments" Stefanie Mangold, Umeå University, has explored ba... Read More
